YOJOzym-PU1LA

-- Pullulanase for Ethanol

YOJOzym-PU1LA is a liquid-type pullulanase preparation made from excellent strain of Bacillus Licheniformis through deep fermentation and extraction technique. Pullulanase is one type of isoamylase which can selectively hydrolyze pullulan, amylase and corresponding α-1, 6-glucosidic in oligosaccharide, thereby, cutting down the whole hydrolysis branch enzyme. Being used with other enzymes (glucoamylase, beta-amylase) can reach the effect of quickening the reaction speed and improving the content of glucose and maltose. It is applied broadly in the industries of starch sugar, organic acid, beer saccharification, modified starch, food, and brewing industries, etc.
